OVERVIEW: The KAB-1500L-Pr is a 1 500 kg-class Russian laser-guided air-to-surface bomb fitted with a deep-penetration warhead for destroying hardened underground or reinforced-concrete targets with high precision.

DETAILS: Designed by GNPP Region (Tactical Missiles Corporation), the bomb belongs to the KAB-1500L family: “L” denotes semi-active laser guidance, “Pr” (penetrator) identifies the reinforced casing and delayed-action fuze. A semi-active laser seeker homes on reflected laser energy from either the launch aircraft or an external designator, giving a CEP of < 7 m from medium- or high-altitude release. The weapon is routinely carried by frontline Russian strike fighters such as the Su-24M and Su-34. Its penetrator warhead can breach several metres of reinforced concrete before detonation, making it suitable for bunkers, C2 nodes and aircraft shelters.
